CESAR DEMARTINI, OF SAN" FRANCISCO, CALIFORNIA, ASSIGNOR OF ONE-HALF TO PETER BACIGALUPI, OF SAN FRANCISCO, CALIFORNIA.

DRIER.

To all whom it may concern f I Be it known that I, CESAR DEMARTINI, a citizen of the United States, residing at San Francisco, in the county ofSan Francisco and State of California, have invented a new and useful Drier, ofwhich the following is a specification.

The device forming the subject matter of this application is adapted to be employed for drying macaroni, spaghetti and like products.

By way of explanation it may be stated that macaroni, spaghetti and thelike must not be dried too rapidly and too completely, lest the product be rendered unduly dry and brittle. Upon the other hand, materials of this sort must not be left in too moist a condition, after partial drying, lest they deteriorate and rot. When the foregoing is clearly understood, it will be appreciated that ina macaroni drier, suitable means must be provided whereby a, proper circulation of air with respect to theprod ucts may be secured;

In view of the foregoing, one object of the present invention is to provide a shaft of novel form, against which the macaroni trays may be placed, novel means being provided, whereby a proper circulation of air through the shaft and through the trays may be secured. v

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the present invention ap pertains. I

With the above and other objects in view which will appear as the description proceeds, the inventionresides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawing :Figure 1 shows in vertical longitudinal section, a macaroni drier constructed in accordance with the present invention; Fig. 2 is a horizontal section of a macaroni drier embodying the present invention; Fig. 3 is a top plan of the macaroni drier, parts being broken away.

In carrying out the present invention there is provided a support 1 which may be Patented Sept. 5,1916.

Application filed March 13, 1916. Serial 1T0, 83,900.

the floor of a room. Resting on the support 1 is a shaft comprising side walls 2, a top 3,

an end wall 4, flaring sides 5, and an end wall 6 connecting the sides. For the shaft above described, the support 1 constitutes a bottom. Disposed within the shaft and extended from the top 3. to the support- 1 which forms the bottom of the shaft is a partition 7. Mounted in the end wall 6 intermediate the top and the bottom of the shaft is an inlet ring 8 carrying a suction fan 9 actuated by a shaft 10. The partition 7 serves-to divide the shaft into. chambers 11 and 12. In one of the side walls 2 there is formed a bottom opening 14 communicat 7 ing with the chamber 11, an intermediate opening 15 communicating with the chamber 11, and an upper opening 16 also communicating with the chamber. In the opposite side wall of the shaft there is formed a bottom opening 17 communicating with the chamber 12, an intermediate opening 18 communicating with the chamber 12, and an upper opening 19 which communicates with the chamber 12. Disposed against the side walls 2 of the shaft, adjacent the flaring walls 5 are posts 20. The end wall 4 proj ects beyond the side walls 2, as indicated at 21 in Fig. 2. Fixed to and upstanding from the support 1 are corner posts 22.

The invention comprises a plurality of trays 23 in which the macaroni, spaghetti or the like is dried, each tray 23 comprising a circumferentially continuous frame and a foraminous bottom 24.

The invention contemplates the use of a plurality of box-like casings 25 comprising a frame 26, a foraminous bottom 27 and a foraminous top 28. One side of each casing is provided with openings 30, the opposite side of the casing being closed as shown at 29. For convenience in describing the operation of the device, the casings in Fig. 1 have been designated by the reference characters 25, 25 and 25*. All of the casings are alike, although arranged differently with respect to other parts of the apparatus.

A pair of bottom trays, denoted in Fig. 1 by the reference character 25 are placed on the support 1, on opposite sides of theshaft, the openings 30 in these trays 25 being disposed against the bottom openings 14 and 17 of the shaft, the closed sides 29 of the trays 25 being outwardly disposed. Upon the casings 25 are piled a series of trays 31 of the sort hereinbefore described. In the top of the trays 31 are placed casings 25 The openings 30 in the casings 25 are outwardly disposed, the closed sides 29 of the trays being placed against the intermediate openings 15 and 18 in the shaft. On top of the-casings 25 are placed piles of trays shown at 32. On the trays are placed casings 25 The openings 30 in the casings 25* are placed against the upper openings 16 and 19 in the shaft, the closed sides of the casings 25 being outwardly disposed. On top of the trays 25 may be placed piles of trays indicated at 88. eration, the trays are slid toward each other, and toward the shaft, in opposite directions, the casings and the trays passing between the posts 22 and being engaged, as illustrated in Fig. 2, between the posts 20 and the portions 21 of the end 4 which project beyond the side walls 2 of the shaft. The various posts 20 and 22 are prolonged upwardly, above the top of the shaft, so that the additional piles 33 of trays may be positioned as shown in Fig. 1.

' When the trays and the casings are located as above described, the suction fan 9 is put into operation. Air is drawn downwardly through the piles 33 of trays, and passes into the shaft through the openings 16 and '19 in the shaft, and through the openings 30 in the casings 25 Air is drawn into the casings 25 through the openings 30 therein, the airpassing upwardly through the piles 32 of trays. The air passes into the casings being drawn downwardly through the trays 31 into the casings 25, the air passing out of the casings 25 through the openings 30 thereof into the shaft, adjacent the bottom of the shaft. All of the air thus delivered into the shaft is sucked out of the shaft by means of the fan 9.

Hinged to one vertical edge of the partition 7, as shown at 37, is a valve 3-1 actuated by a spindle 35 passingupwardly through the top 3 of the shaft, the spindle being provided with an exposed hand wheel 36,

In practical op 25, through openings 30, this air' whereby the valve 34 may be swung from its sides; a plurality of superposed casings each having a closed side and an open side,

the casings being open for the passage of air therethrough, the closed sides of certain of the casings being disposed against certain of the openings in the shaft, and the open sides of others of the casings being disposed against the others of the openings in the shaft; trays located between the easings and having foraminous bottoms; and a suction means communicating with the shaft intermediate the upper and lower ends of the shaft and'located between the uppermost and the lowermost of the openings in the shaft.

2. In a drier of the class described, an upright shaft; an upright partition within the shaft and dividing the shaft into side chambers, the side walls of the shaft having openings communicating with the chambers; a draft producing means communicating withthe shaft at one edge of the shaft and intermediate the upper and'lower ends of the shaft; a valve movablyconnected with one vertical edge of the partition and movable to close olfeither of the chambers with respect to the draft producing means; and means for operating the valve.

In testimony that I claim the foregoing as my own, I have hereto afliXed' my'sign'ature in the presence of two witnesses.
